I think this is a pretty rare carburetor. 4 speed carb 7040243 date code 0280. Carb has not been rebuilt. It will need a rebuild. This carb is probably harder to find than a stage 1 carb. Ive had this carb for 7 or 8 years and have no plans for it. Time to let some one else have it that needs it. Asking $2000 will consider partial trades. More pics available on request Srrious enquiries only. Thanks
